Corona 2D will be open sourced under the GNU GPLv3 license, while offering the option of a commercial license upon agreement with Corona Labs. In April 2020, the engine was renamed from Corona SDK to Solar2D. This was done in response to the closure of Corona Labs, as well as the COVID-19 pandemic. Corona Labs also stopped offering commercial licenses and changed its open source license from GPLv3 to the more permissive MIT License. Major features Solar2D's API suite features API calls for audio and graphics, cryptography, networking and device information such as accelerometer information, GPS, and user input as well as widgets, particle effects, and more.
